Thanks Dr. Rajput. I'm going to consult physician next month.
Hi, welcome to the forum, Reasons for cold extremities can be due to vitamin B12, B1 and B6 deficiency, nerve injury, diabetic neuropathy, cervical sponylosis, frostbite, peripheral vascular disease, hypothyroidism etc. It is typically seen in hypothyroid condition wherein the person is intolerant to cold and it can be associated with other symptoms like constipation, change in voice etc.
For confirmation you can check your sugar level, thyroid status etc. You may have to take vitamin B-complex supplements. I suggest you to consult physician. Take care and regards.
